In 'This Must Be the Place,' Sean Penn plays a retired rock star who sets out to find his father's executioner, an Nazi war criminal who is a refugee in the U.S. Not much else is known about the Paolo Sorrentino–directed film. Well, except Frances McDormand is also in it; we do know that.

The trailer offers up more questions about the film than it provides answers. First, why is Penn made up to look like Robert Smith? Second, is the character, um, affected in some way? And what is that dog doing at the bottom of an empty pool?

It all feels very arty.

'This Must Be the Place' is set to hit theaters later this year. Check out the trailer after the jump.
